Former Rolling Stones bassist Bill Wyman says he was "disappointed" by only playing on two songs at the Stones' two London anniversary shows in November.

Wyman, who joined his old friends for "Honky Tonk Women" and "It's Only Rock 'n' Roll (But I Like It)," says, "In December 2011, Keith Richards called and said, 'Come on mate, why don't you have a jam with us?' Then they asked if I'd be interested in getting involved in the band for a special occasion. I thought I would get quite heavily involved, so when they said they only wanted me to do two songs I was a bit disappointed. I only had one rehearsal and no soundcheck so I just winged it. It was great, but I didn't want to go to America for two songs. I think they understood. Well, Charlie Watts did."

Wyman doesn't like to fly. Former Stones guitarist Mick Taylor played on one song in London as well as in Newark, New Jersey in December.

The latest tour rumor has the Stones doing U.S. shows in June and again at the end of the summer with South America and other parts of the world after that.
